PC to PS4 Switch

[HEC]

That's indeed ABSOLUTELY incorrect - you'll ofcourse get another 30 days for each new platform you register (so for PC + PS3 + PS4 you can get up to 90 days). If you have (access to) PS3 you can also purchase much cheaper PS3 version of the game, register it and log into the game at least once on PS3 and then upgrade it to PS4 version via Mogstation for free. You'll receive free 30 days as well.
